“…Of course, the use of fluids as a constituent material for photonic devices presents a number of technological challenges, such as the integration of liquid-state elements into traditional solid-state microphotonic systems [169,170]. Nevertheless, liquid-state devices can offer a number of potentially transformative advantages for microphotonic systems [114,115,118]. Moreover, there have been successful examples of liquid-state and gas-state devices that are compatible with conventional solidstate photonics such as liquid-state optical lenses [171], liquid-core optical fibres used in spectroscopy [172] and gas-filled optical fibres used to generate optical frequency combs [173,174].…”

“…Although the conversion of acoustic nonlinearity of bubbles and droplets into the optical domain has not been in the focus of previous works, there have been several highly relevant demonstrations of optical signal generation from capillary waves in liquid droplets [117,118]. The most relevant results demonstrated in those works will be overviewed below.…”

Nonlinear optical processes are vital for fields including telecommunications, signal processing, data storage, spectroscopy, sensing, and imaging. As an independent research area, nonlinear optics began with the invention of the laser, because practical sources of intense light needed to generate optical nonlinearities were not previously available. However the high power requirements of many nonlinear optical systems limit their use, especially in portable or medical applications, and so there is a push to develop new materials and resonant structures capable of producing nonlinear optical phenomena with low-power light emitted by inexpensive and compact sources. Acoustic nonlinearities, especially giant acoustic nonlinear phenomena in gas bubbles and liquid droplets, are much stronger than their optical counterparts. Here, we suggest employing acoustic nonlinearities to generate new optical frequencies, thereby effectively reproducing nonlinear optical processes without the need for laser light. We critically survey the current literature dedicated to the interaction of light with nonlinear acoustic waves and highly-nonlinear oscillations of gas bubbles and liquid droplets. We show that the conversion of acoustic nonlinearities into optical signals is possible with low-cost incoherent light sources such as lightemitting diodes, which would usher new classes of low-power photonic devices that are more affordable for remote communities and developing nations, or where there are demanding requirements on size, weight and power. . 1: (a) Generation of new optical frequencies via a nonlinear optical interaction. High-power monochromatic laser light interacts with the nonlinear optical medium, e.g. a dielectric microresonator, to generate new optical frequencies [9]. (b, c) The nonlinear properties of sound can be used to generate optical nonlinearities without the need for high-power laser light. Low-power light couples to a sound wave via a deformable fluid, e.g. gas bubble or liquidmetal nanoparticle, exploiting strong nonlinear acoustic effects. This converts acoustic frequencies to the optical domain, effectively reproducing the result of the nonlinear optical interaction in (a). Images from www.freeimages.com and www.dreamstime.com. FIG

“…The demonstration of fibre based coupling [66] is significant in this regard -this method is heavily used by the solid whispering gallery mode community, and may offer new flexibility in controlled coupling, and enable studies to be carried out between multiple droplets [191], as well as connected droplets [192]. Very recent work has made use of this technique to produce a new class of lasersripplon lasers [193] -in which Raman class lasers are made using capilliary waves in an optically trapped droplet. Methods making use of elastomers would seem to offer the best chance of high parallelization, with microfluidics offering the best option for high throughput control.…”

Abstract. It is perhaps surprising that something as fragile as a microscopic droplet could possibly form a laser. In this article we will review some of the underpinning physics as to how this might be possible, and then examine the state of the art in the field. The technology to create and manipulate droplets will be examined, as will the different classes of droplet lasers. We discuss the rapidly developing fields of droplet biolasers, liquid crystal laser droplets and explore how droplet lasers could give rise to new bio and chemical sensing and analysis. The challenges that droplet lasers face in becoming robust devices, either as sensors or as photonic components in lab on a chip devices is assessed.

“…In this work, we report a new acoustic-based highthroughput technique for measuring the compressibility of single particles without physical contact, using an opto-mechano-fluidic resonator (OMFR) [16,17]. These fused silica microcapillary resonators are cavity optomechanical sensors [18][19][20][21][22] that support ultrahigh-Q optical modes coupled to co-localized mechanical (phonon) modes of the structure. Fluid analytes can be flowed internally without influencing the optics ( Fig.…”

High-throughput label-free measurements of the optical and mechanical properties of single microparticles play an important role in biological research, drug development, and related large population assays. Mechanical detection techniques that rely on the density contrast of a particle with respect to its environment are blind to neutrally bouyant particles. However, neutrally buoyant particles may still have a high compressibility contrast with respect to their environment, opening a window to detection. Here we present a label-free high-throughput approach for measuring the compressibility (bulk modulus) of freely flowing microparticles by means of resonant measurements in an opto-mechano-fluidic resonator.
